This post, containing a nice slew of methods of trisecting a general angle using neusis methods, can be found at Numbers and Shapes.
You can find this post, introducing geometric constructions which allow the use of a straight-edge with two marks, at my new site Numbers and Shapes.
This post, which is on my new site here: http://www.numbersandshapes.net/?p=2520 shows how a cubic equation can be solved by origami. This is not a new result by any means, but it’s hard to find a simple proof of how the

In my last post I mentioned the new language Julia. It deserves more than a single paragraph, so I thought I’d walk through a problem, and tackle it with the language. The problem is a stock standard one: investigating the
Over two years ago I wrote The best Matlab alternative with a follow-up a bit later, which seem to have engendered a far amount of discussion. Well, things have moved on in the computational world, and a user is now
In the interests of random number generation, I’ve been experimenting with the iteration for a prime and a primitive root . Now, it turns out that some primes have a primitive root which generates all non-zero residues, and others don’t.
